Electrical Wiring

Do not connect electrical power to the unit until all electrical wiring has been completed.
This appliance must be electrically grounded in accordance with local codes, or in the absence of local codes,
with the National Electrical Code, ANSI/NFPA 70. In Canada, the latest CSA C22.1 Electrical Code.
Caution: Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper
and dangerous operation.
Verify proper operation after servicing.
Field wiring to be performed at time of appliance installation.
Caution
• The electrical supply required by the water
heater is 120V AC at 60 Hz.
The power consumption may be up to 355W or
higher if using optional accessories.
Use an appropriate circuit.
• Do not disconnect the power supply when not
in use. When the power is off, the freeze
prevention in the water heater will not acti-
vate, resulting in possible freezing damage.
Ground
• To prevent electrical shock, provide a ground
with resistance less than 100 . An electrician
should do this work.
• A grounding screw is provided on the back of
the junction box lid.
Do not connect the ground to the city water
or gas piping. Do not tie the ground to a tele-
phone line.
Breaker Installation
• Mount a device which shuts off the electrical
path automatically (leakage breaker) when
electrical leakage is detected.
Do not turn on the power until the electrical wiring is finished.
This may cause electrical shock or damage to the equipment to occur.
Consult qualified electrician
for the electrical work.
• Do not let the power cord contact the gas piping.
Tie the redundant power cord outside the
water heater. Putting the redundant length of
cord inside the water heater may cause elec-
trical interference and faulty operation.
